tires Acura RDX 2011 Owner's Guide

Your tires have wear indicators
molded into the tread. When the
tread wears down, you will see a 1/2
inch (12.7 mm) wide band across the
tread. This shows there is less than
1/16 inch (1.6 mm) of tread left on
the tire.
A tire this worn gives very little
traction on wet roads. You should
replace the tire if you can see three
or more tread wear indicators.Tire Service Life
The service life of your tires is
dependent on many factors,
including, but not limited to, driving
habits, road conditions, vehicle
loading, inflation pressure,
maintenance history, speed, and
environmental conditions (even
when the tires are not in use).
In addition to your regular
inspections and inflation pressure
maintenance, it is recommended that
you have annual inspections
performed once the tires reach five
years old. It is also recommended
that all tires, including the spare, be
removed from service after 10 years
from the date of manufacture,
regardless of their condition or state
of wear.
The last four digits of the TIN (tire
identification number) are found on
the sidewall of the tire and indicate
the date of manufacture (See
Tire
Labeling on page 484). Tire Maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check the
wheel alignment.
Have your dealer check the tires if
you feel a consistent vibration while
driving. A tire should always be
rebalanced if it is removed from the
wheel. When you have new tires
installed, make sure they are
balanced. This increases riding
comfort and tire life. For best results,
have the installer perform a dynamic
balance.
Improper wheel weights can damage
your vehicle's aluminum wheels. Use
only Acura wheel weights for
balancing.

Tire RotationTo help increase tire life and
distribute wear more evenly, rotate
the tires according to the
maintenance messages displayed on
the multi-information display. Move
the tires to the positions shown in
the illustration each time they are
rotated. If you purchase directional
tires, rotate only front-to-back.Replacing Tires and Wheels
Replace your tires with radial tires of
the same size, load range, speed
rating, and maximum cold tire
pressure rating (as shown on the
tire's sidewall).
Mixing radial and bias-ply tires on
your vehicle can reduce braking
ability, traction, and steering
accuracy. Using tires of a different
size or construction can cause the
ABS and vehicle stability assist
system (VSA) to work inconsistently.
The ABS and VSA system work by
comparing the speed of the wheels.
When replacing tires, use the same
size originally supplied with the
vehicle. Tire size and construction
can affect wheel speed and may
cause the ABS or VSA system to
activate.
It is best to replace all four tires at
the same time. If that is not possible
or necessary, replace the two front
tires or two rear tires as a pair.
Replacing just one tire can seriously
affect your vehicle's handling.
If you ever replace a wheel, make
sure that the wheel's specifications
match those of the original wheels.
Also be sure you use only TPMS
specific wheels. If you do not, the tire
pressure monitoring system will not
work.
Replacement wheels are available at
your dealer.

Installing improper tires on your
vehicle can affect handling and
stability. This can cause a crash
in which you can be seriously
hurt or killed.
Always use the size and type of
tires recommended in this
owner's manual.Wheel and Tire Specifications
Wheels:
18 x 7 1/2J (TPMS)
Tires:
P235/55R18 99V
See page 482 for information about
DOT Tire Quality Grading, and page
484 for tire size and labeling
information. Winter Driving
Tires marked
‘‘M ＋ S’’ or ‘‘All
Season ’’on the sidewall have an all-
weather tread design suitable for
most winter driving conditions.
For the best performance in snowy
or icy conditions, you should install
snow tires or tire chains. They may
be required by local laws under
certain conditions.
Snow Tires
If you mount snow tires on your
vehicle, make sure they are radial
tires of the same size and load range
as the original tires. Mount snow
tires on all four wheels. The traction
provided by snow tires on dry roads
may be lower than your original tires.
Check with the tire dealer for
maximum speed recommendations.
Tires44810/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu

Tire Chains
Mount tire chains on your tires when
required by driving conditions or
local laws. Install them only on the
front tires.
Because your vehicle has limited tire
clearance, Acura strongly
recommends using the chains listed
below, made by Security Chain
Company (SCC).
Cable type: Shur Grip Z
SZ343When installing cables, follow the
manufacturer's instructions, and
mount them as tight as you can.
Make sure they are not contacting
the brake lines or suspension. Drive
slowly with them installed. If you
hear them coming into contact with
the body or chassis, stop and
investigate. Remove them as soon as
you begin driving on cleared roads.
Traction devices that are the wrong size
or improperly installed can damage
your vehicle's brake lines, suspension,
body, and wheels. Stop driving if they
are hitting any part of the vehicle.
Using the wrong chains, or not
properly installing chains, can
damage the brake lines and
cause a crash in which you can
be seriously injured or killed.
Follow all instructions in this
owner's manual regarding the
selection and use of tire chains.

●Block the rear wheels.●If the vehicle is to be stored for a
longer period, it should be
supported on jackstands so the
tires are off the ground.●Leave one window open slightly (if
the vehicle is being stored
indoors).●Disconnect the battery.●Support the front and rear wiper
blade arms with a folded towel or
rag so they do not touch the
windshield.●To minimize sticking, apply a
silicone spray lubricant to all door
and tailgate seals. Also, apply a
vehicle body wax to the painted
surfaces that mate with the door
and tailgate seals.
●Cover the vehicle with a
‘‘breathable ’’cover, one made from
a porous material such as cotton.
Non-porous materials, such as
plastic sheeting, trap moisture,
which can damage the paint.●If possible, periodically run the
engine until it reaches full
operating temperature (the cooling
fans cycle on and off twice).
Preferably, do this once a month. Interior Care
Leather
Vacuum dirt and dust from the
leather frequently. Pay close
attention to the pleats and seams.
Clean the leather with a soft cloth
dampened with a 90% water and 10%
neutral wool detergent solution.
Then buff it with a clean, dry cloth.
Remove any dust or dirt on leather
surfaces immediately.

Use the compact spare tire as a
temporary replacement only. Get
your regular tire repaired or
replaced, and put it back on your
vehicle as soon as you can.
Check the inflation pressure of the
compact spare tire every time you
check the other tires. It should be
inflated to:
60 psi (420 kPa , 4.2 kgf/cm
2)Follow these precautions:
●Never exceed 50 mph (80 km/h).●This tire gives a harsher ride and
less traction on some road
surfaces. Use greater caution while
driving.●Do not mount snow chains on the
compact spare tire.●Do not use your compact spare tire
on another vehicle unless it is the
same make and model.●After the flat tire is replaced with
the spare tire, the low tire
pressure/TPMS indicator stays on.
After several miles (kilometers)
driving with the spare, this
indicator begins to flash, then
stays on again. You will also see a
‘‘
CHECK TPMS SYSTEM’’
message on the multi-information
display (see page 393).
Replace the tire when you can see
the tread wear indicator bars. The
replacement should be the same size
and design tire, mounted on the
same wheel. The spare tire is not
designed to be mounted on a regular
wheel, and the spare wheel is not
designed for mounting a regular tire.

If your vehicle needs to be towed,
call a professional towing service or
organization. Never tow your vehicle
with just a rope or chain. It is very
dangerous.(On SH-AWD models)The only way you can safely tow
your vehicle is with flat-bed
equipment.The operator will load
your vehicle on the back of a truck.
Any other method of towing will
damage the drive system. When you
contact the towing agency, inform
them a flat-bed is required.Towing with only two tires on the
ground will damage parts of the all-
wheel-drive system. Your vehicle should
be transported on a flat-bed truck or
trailer.
(Execpt SH-AWD models)There are two ways to tow your
vehicle:Flat-bed Equipment
－ The operator
loads your vehicle on the back of a
truck. This is the best way to
transport your vehicle.
Wheel-lift Equipment
－ The tow
truck uses two pivoting arms that go
under the front tires and lift them off
the ground. The rear tires remain on
the ground. This is an acceptable
way to tow your vehicle. If, due to damage, your vehicle must
be towed with the front wheels on
the ground, do this:
●Start the engine.●Shift to the D position and hold for
5 seconds, then to N.●Turn off the engine.●Leave the ignition switch in the
ACCESSORY (I) position so the
steering wheel does not lock.●Release the parking brake.

The tires on your vehicle meet all
U.S. Federal Safety Requirements.
All tires are also graded for
treadwear, traction, and temperature
performance according to
Department of Transportation (DOT)
standards. The following explains
these gradings.
Uniform Tire Quality Grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and
maximum section width. For
example:Treadwear 200
Traction AA
Temperature A
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades. Treadwear
The treadwear grade is a
comparative rating based on the wear
rate of the tire when tested under
controlled conditions on a specified
government test course. For
example, a tire graded 150 would
wear one and one-half (1 1/2) times
as well on the government course as
a tire graded 100. The relative
performance of tires depends upon
the actual conditions of their use,
however, and may depart
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate.
Traction
The traction grades, from highest to
lowest, are AA, A, B, and C. Those
grades represent the tire's ability to
stop on wet pavement as measured
under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction
performance.
Warning: The traction grade
assigned to this tire is based on
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.DOT Tire Quality Grading (U.S. Vehicles)48210/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu
